    Activity patterns by two colour morphs of the vulnerable guina, Leopardus guigna (Molina 1782), in temperate forests of southern Chile
    (2015) Hernandez, Felipe; Galvez, Nicolas; Gimona, Alessandro; Laker, Jerry; Bonacic, Cristian
    Here we provide the first analysis of activity patterns exhibited by spotted and melanistic colour morphs of the vulnerable guina Leopardus guigna, in a forest landscape of southern Chile. Camera traps showed guinas were mainly active at night (64% of photos). Melanistic guinas were more nocturnal (82% of photos) than the more common spotted cats (57%). Spotted guinas were more active on cloudy and moonless nights. Our study provides novel findings about the behavioural plasticity of guina in different ambient conditions, and the relative advantage to each colour morph to persist in an increasingly human-dominated landscape.

    Analysis of the echolocation calls and morphometry of a population of Myotis chiloensis (Waterhouse, 1838) from the southern Chilean temperate forest

    G. Ossa, J.T. Ibarra, K. Barboza, F. Hernandez, N. Galvez, J. Laker, and C. Bonacic. 2010. Analysis of the echolocation calls and morphometry of a population of Myotis chiloensis (Waterhouse, 1838) from the southern Chilean temperate forest. Cien. Inv. Agr. 37(2): 131-139. Echolocation is characteristic of bats of the suborder Microchiroptera. Though recent studies of echolocation calls in Latin America have generated significant advances in knowledge about distribution, habitat use and ecology of bats, the recording and analysis of bat calls is barely known in Chile. As a first step in studies on the ecology of the endemic Chilean myotis bat (Myotis chiloensis), we carried out morphometric measures and analyzed echolocation calls in a rural site near Puck (39 degrees 15'S 17 degrees W) in the Araucania Region of southern Chile. During January 2009, we obtained 22 records from captured and 75 records from flying individuals. The analysis of calls in searching phase showed that the terminal frequency for this species is 43.4 +/- 1.2 kHz, with a mean duration of 2.1 +/- 1.0 ms and an interval between pulses of 77.5 +/- 16.9 ms. The calls are FM - QCF, as is characteristic for the family Vespertilionidae. The contribution of new morphometric data from captured and released individuals indicates differences from previous studies. The records and acoustic analysis establishes a baseline for more detailed future ecological investigation of this and other bat species in Chile.
